V130LS20CP Equivalent & Substitute Parts

Part Overview

The V130LS20CP is a 205 V, 10 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the C-III series. This through-hole disc component (14mm) is designed for transient voltage protection applications requiring high surge current capacity and energy absorption. The part is currently active in production with 923 units in stock. Equivalent and substitute parts may be required due to inventory constraints, lead time considerations, or specific application requirements for alternative package configurations or thermal operating ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V130LS20CP is based on the following critical electrical and mechanical parameters:

• Varistor Voltage (Typ): 205 V nominal voltage rating must be maintained
• Current - Surge: 10 kA surge current capacity requirement
• Maximum AC Volts: 130 V AC rating
• Number of Circuits: Single circuit configuration
• Mounting Type: Through hole technology
• RoHS Compliance: ROHS3 Compliant status

The substitute part B72220S2131K101 meets all core electrical specifications. Differences in package size (20mm vs. 14mm disc), energy rating (100 J vs. 200 J), and operating temperature range represent trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the V130LS20CP and B72220S2131K101 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications.

The V130LS20CP offers a 200 J energy rating with a compact 14mm disc package and extended low-temperature operating range (-55°C). This configuration is optimal for space-constrained applications or systems requiring operation in cold environments.

The B72220S2131K101 provides an extended high-temperature operating range (-40°C to 105°C) with a larger 20mm disc package but reduced energy rating (100 J). This substitute is appropriate for applications with elevated ambient temperatures or where the larger package footprint is acceptable.

Selection between these parts should be based on: (1) available PCB space for the package size difference, (2) application operating temperature requirements, and (3) energy absorption demands of the specific transient voltage protection circuit.

Frequently Asked Questions (FAQ)

Q: Can B72220S2131K101 directly replace V130LS20CP in all applications?

A: Both parts share identical varistor voltage ratings (205 V typ), surge current capacity (10 kA), and AC voltage ratings (130 V). However, the substitute has a lower energy rating (100 J vs. 200 J) and different package dimensions (20mm vs. 14mm disc). Application-specific energy requirements and PCB layout constraints must be evaluated.

Q: What is the significance of the energy rating difference?

A: Energy rating indicates the maximum transient energy the varistor can absorb. The V130LS20CP's 200 J rating provides greater energy absorption capacity than the B72220S2131K101's 100 J rating. Applications with high-energy transient events may require the higher energy-rated part.

Q: Are there packaging considerations for substitution?

A: Yes. The V130LS20CP uses a 14mm disc package while B72220S2131K101 uses a 20mm disc package. PCB layout and available mounting space must accommodate the larger footprint of the substitute part.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for restricted substance use and environmental compliance.

Q: How do operating temperature ranges affect substitution?

A: The V130LS20CP operates from -55°C to 85°C, while B72220S2131K101 operates from -40°C to 105°C. Applications requiring operation below -40°C require the V130LS20CP. Applications requiring sustained operation above 85°C benefit from the extended range of B72220S2131K101.
